A STUDY OF SUBGRADE PRESSURE OF RAILROADS

For the purpose of refining the procedure of subgrade pressure evaluation, subgrade and rail pressure under traffic loading was observed in an attempt to form a clearer and firmer conception of subgrade pressure acting on railroad subgrade. Details of measurements of subgrade and rail pressure are provided and 11 conclusions drawn. Also covered are the following topics: theoretical derivation of rail pressure from rail deflection analysis and subgrade pressure as illustrated by the model of track system.
